Russian authorities say that a wave of anonymous bomb threats is continuing with fresh threats in the North Caucasus.

Authorities in Daghestan said on September 22 they evacuated hundreds of students and teachers from four secondary schools and two universities in the regional capital, Makhachkala, after receiving a phoned-in bomb threat.

On September 21, authorities in another North Caucasus region, North Ossetia, said they had to evacuate hundreds of people from 18 buildings in the regional capital, Vladikavkaz, in two days after receiving similar phone calls.

Evacuations stemming from bomb threats also continued in Moscow. Russian news agencies quoted Moscow police as saying that 20 buildings were evacuated on September 22 after anonymous bomb threats were made by phone.

Tens of thousands of people have been evacuated from schools, malls, theaters, universities, hotels, and government buildings in cities across Russia since September 10 following anonymous bomb threats.

Bombs have not been discovered in any of the cases.

Kremlin spokesman Dmitry Peskov said on September 14 that the threats were "telephone terrorism" and that "all necessary measures are being taken" to find the perpetrators.
